BEAM AND GIBDER MOLD.

Specification of Letters Patent.

Patented Feb. 15, 1916.

Application filed February 20, 1915. Serial No. 9,515.

' ABLE, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Beam and Girder Molds, of which the following is a specification.

The invention relates to beam and girder molds, and particularly to the mold construction at the intersection of a girder and beam. The invention has for its primary objects, the provision, in a construction of the kind specified, of an improved adjust able corner connection; the provision of a lap corner connection for beams and girders arranged to give any and every adjustment which conditions may require; and the provision of a corner connection of the kind specified, so arranged as to permit of a most ready and convenient assembling and disassembling of the mold parts. One embodiment of the invention is illustrated in the accompanying drawings wherein- Figure 1 is a perspective view showing my improved construction; Fig. 2 is a plan view of the apparatus with some of the parts broken away; and Fig. 3 is a section on the line III-III of Fig. 2.

Referring to the drawings; 1, 2, 3 and 4 are a number of the panels which go to make up a girder; 5 and 6 are a pair of opposing beam panels; 7 and 8 are lap corner panels connecting the girder and beam panels;-9 is a girder splice plate; 10 is a girder connecting bar; 11 and 12 are shores for supporting the girder from beneath; and 13 and 14 are the planks constituting the bottom members of the girder and beam, respectively.

Both the girder and beam panels are provided at their upper and lower edges with outwardly turned flanges as illustrated, and the lap corner panels are provided at their upper edges only with. outwardly turned flanges and overlapping the flanges of the panels. The girder panels are provided with airs of vertical stiffening angles 16 and'17 placed intermediate the ends of the panels and with other vertical angles 18 and 19 at the ends of the panels, such latter angles having their flanges perforated and serving as connection means with the next adjacent panels. Opposing-ggirderpanels,

' such as 1 and 2, are connected together by means of gage plates 20 and- 21 which serve to hold the panels in parallelism, the ends of the gage plates being secured by means of pins 22. The beam panels 5 and 6 are similar to the girder panels 1 and 2 except their depth is less, such beam panels being onl 80f the depth of the lap corner panels 7 an The mezins by which the lap corner panels are secured adjustably to the beam and girder panels will be seen by reference to Figs. 2 and 3 lll'COIlIIQCtlOIl with Fig. 1.

The connections for the panels 7 and 8 are similar so that a description of one will suffice for both.

As indicated in Fig. 2, the vertical end edges of the panels 2 and 5 are provided with angles 23 and 24, such angles being similar to the angles 18 and 19 illustrated in Fig.1. Bolted to the flanges of these angles are the angles 25 and 26, the free wings of which, as indicated in Fig. 8, are provided with a plurality of horizontal slots 27. See also similar angle 25 with slots 27 at left hand end of panel 2 in Fig.

1. The lap corner panel 7 is provided with a plurality of rows of holes 28 (Fig. l) and this panel is secured to the angles 25 and 26 by means of stove bolts 29 which extend through the holes in the lap corner pane and through the slots 27 in the wings of the angles 25 and 26. This arrangement gives any and all desired adjustments since the slots 27 in the arms or flanges of the angles 25 and 26 lying next the lap plates 7 give adjustments lying between the holes in the rows 28.

Lying below the-panels 7 and 8 and serving to connect the girder panels 2 and 4 is the girder splice plate 9 having at its lower edge an inwardly turned flange 30. This splice plate is provided with rows of holes 31 and stove bolts 32 extending through 'position, the bars 10 being used at the breaks in the girder at which beams are to intersect. The girder is then raised to 0 sition and supported by means of the shores 11 and 12. The beams are then assembled with the lap corner panels secured thereto and placed in the position illustrated with the ends of the beams resting on the brackets 33 carried by the splice plates 9, the bars 10 being removed at such time.

The advantage of the construction lies in the fact that it maybe very readily assembled and disassembled. The construction may be used with different spacing of beams and with beams of any height or width, any desired adjustment of the parts may be secured by the use of the lap corner panels and splice plates, and a very secure and effective connection is secured at the intersection of the beams and girders. Other ad- 'vantages incident to the construction will be readily apparent to those skilled in the art.

What I claim is:

1. In combination, a pair of alined' girder panels with their ends spaced apart, a pair of opposing beam panels at right angles to the girder panels of less depth than such girder panels with their ends adjacent the space between the girder panels, a pair of lap corner panels each having apair of wings which are at right angles to each other and overlap the inner faces of the girder and beam panels, and a girder splice plate overlapping the inner faces of the girder panels and lying beneath the lap corner panels.

2. In combination, a pair ofalined girder panels with their ends spaced apart, a pair of opposing beam panels at right angles to the girder panels of less depth than such girder panels with their ends adjacent the space between the girder panels, a pair of lap corner panels each having a pair of wings which are at right angles to each other and overlap the inner faces of the girder and beampanels, a girder splice plate overlap-' ping the ends of the girder panels and lying beneath the lap corner panels and the beam, and a supporting bracket for the beam panels secured to the outer face of the girder splice plate and projecting beneath the lap corner panels.

3. In combination, a pair of alined girder panels with their ends spaced apart, a pairof opposing beam panels 'at'right angles to the girder panels of-less depth than such girder panels with their ends adjacent the space between the girder panels, a pair of lap corner panels each having a pairof wings which are at right angles to each other and overlap "the inner faces of the girder and beam panels, and a girder splice plate overlapping the inner faces of the girder panels and lying beneath the lap corner panels, the saidsplice plate extending 4. In combination, a pair of alined girder panels'with their ends spaced apart, a pair of opposing beam panels at right angles to the girder panels of less depth than such girder panels with their ends adjacent the space between the girder panels, a pair of lap corner panels each having a pair of wings which are at right angles to each other and overlap the inner faces ofthe girder and beam panels, a girder splice plate overlapping the inner faces of the girder panels and lying beneath the lap corner panels, means whereby the lap panels are secured adjustably to the girder and beam girder and beam panels, and a 'rder splice plate overlapping the inner aces of the girder panels and lying beneath the lap corner panels, the said lap corner panels having adjustable connections with the beam and girder panels, and the girder splice plate having adjustable connections at its ends with the girder panels.
